Answer:
the surface area is 133cm.
7 x 7 is 49
7 x 6 is 42.
42 divided by 2 is 21.
21 x 4 is 84
So 84 + 49 is 133.
Let’s see..................
Answer:
Hello,
Answer :Rotation of 90° clockwise by the origin O, and translation 2 units to the left
Step-by-step explanation:
We know that
The formula to <span>find the sum of the interior angles of a regular polygon is
</span>(n - 2)*180°
where n is the number of sides
so
clear n
(n - 2)*180° = 720°-----> (n-2)=720/180---> n-2=4----> n=6 sides
the answer is
6 sides
Answer:
△ GHI ≅ △ JKL. (Proved)
Step-by-step explanation:
In triangle Δ GHI, GI = 5 and HI = 4.
If we consider the triangle is a right triangle having hypotenuse = 5 and any other leg = 4.
Then this will follow the Pythagoras theorem as 3² + 4² = 5², where 3 is the other leg.
Therefore, Δ GHI is a right triangle having hypotenuse 5 and one leg 4.
Similarly, we can prove that △ JKL is also a right triangle(Since JK = 4 and JL = 5), having hypotenuse 5 and one leg 4.
Therefore, applying HL rule, we cam conclude △ GHI ≅ △ JKL. (Proved)
